Cannot read properties of undefined (reading 'x')

Hi all!
I was wondering if anyone would be able to help. I’ve uploaded a GLB of a rigged character and I’m getting this error. Does anyone know what could be causing it? The character seems to run okay en the editor, but I get the error when i try “open in viewer” which is causing knock on effests when trying to use it with Umbraco. Unfortunately I can’t share much more than that, but any help would be appreciated.

The link was invalid. Please, provide a link to the project that can reproduce the issue.

Hi @Robert_Foley and welcome!

A link to a project is indeed the most useful for other users to be able to help. You can also upload an image directly to your post. Unknown links are not appreciated.
